The London Stock Exchange "has made a very strong case" for oil giant Saudi Aramco to choose Britain for its expected 2 trillion (£1.5 trillion) flotation, a spokesman for Prime Minister Theresa May has said.

During my time as an MP, the oil and gas market has been incredibly challenging for service companies and operators working in the industry. When I was first elected in May 2015 the oil price was around $62 a barrel, then dropped to around $30 before rising back up to $52. The quick and sudden decline from the $100-a-barrel 2014 rates has really dented confidence and I know it has left some companies struggling to find capital finance.
